Steering Angle Sensor Range/Performance Problem
The steering angle sensor is reporting a signal outside its expected range.
Heads up: this code wasn't in our hand-written library yet, so DiagCoach AI built this page on the fly. Double-check critical specs against service info before condemning parts.
What it means (plain English)
The steering angle sensor tells the computer how much and in which direction you are turning the steering wheel. If it gives readings that are too high or too low, the system can't help you steer correctly.
What the computer is actually seeing
The computer expects the steering angle sensor to output a voltage between 0.5V and 4.5V, corresponding to its range of motion. If it sees voltage readings falling outside this range, it sets the C1326 code.
What a healthy reading looks like
0.5V to 4.5V depending on steering angle position.
Guided diagnostic — the DiagCoach way
Don't just throw parts at it. Walk through these in order — each step tells you whether to keep going or stop and fix what you found.
- 11. Inspect the steering angle sensor wiring and connectors for damage or corrosion. Check for any disconnections or shorts. If any issues are found, repair the wiring.
- 22. Check the sensor's output with a multimeter. Disconnect the sensor and measure the voltage output while manually turning the wheel. Voltage should move smoothly between 0.5V and 4.5V as you turn. If not, replace the sensor.
- 33. If the wiring and sensor check out, confirm that the sensor is properly calibrated according to the manufacturer's specifications. Use a scan tool to perform steering angle sensor calibration. If the code returns, it may need replacement.
Common causes
- Faulty steering angle sensor
- Wiring issues in the sensor circuit
- Improper calibration of the steering angle sensor

Frequently asked questions
Can I still drive with this code?
Yes, but steering assistance features may not function correctly, impacting vehicle handling.
Will this code return after clearing it?
It may return if the underlying issue isn’t fixed, such as a sensor malfunction or a wiring problem.
Why does this code appear with others like C1325?
They indicate related steering sensor faults; they often occur together due to shared components or wiring.
